TELEscoPIcBED.

Specification of Letters Patent, 1 Patented De@ 2, 17.913,

Application filed June 17,1919.v Serial'No. 304,908.

To all whom t may concern: I

Be it known that I, FRANoisZnK DUDEK, a citizen of Poland, residing at 309 Power street, Johnstown, county of Cambria, and State of Pennsylvania, have invented certain new and useful Improvements in Telescopic Beds, of which the following is a specication.

This invention has for its object the provision of a bed which may be extended both f laterally and longitudinally so as to'be used by one or more adults or children as desired.

A further Object is to provide a bed which may be telescopically folded or collapsed when not in use so as to occupy a minimum of space.

These and other like objects are attained by the novel construction and combination of parts hereinafter described, and shown in the accompanying drawings, forming a material part of this disclosure and in which*- Figure 1 is a top plan View showing a bed frame made in accordance with the invention, extended at full length.

Fig. 2 is an end view of the same.

Fig.'3 is a fragmentary end view showing the connecting elements in a partially eX- tended position.

Fig. t is a similar view of the same, showing the parts further extended, preparatory to folding.

Fig. 5 is an enlarged longitudinal sectional view taken through the end connecting elements, and K Fig. 6 is a side elevational View showing the complete frame of the bed in a folded position.

Referring to the drawings in detail, the numeral 10 designates the tubular corner posts or legs, all of which are alike and furnished at their bottoms with enlarged rounded contacts 11, taking the place of ordinary casters, knobs or like ornamental devices 12 being attached at their upper ends. Rigidly engaged with the diagonally opposite corner posts are tubular side bars 14,

the saine being telescopically received by larger tubular bars 15 attached to the diagonally opposite corner posts, the smaller bars being receivable within the larger. The bars l5 have lateral slots into which the extensions 16, formed near the ends of the bars 14 operate so as to lprevent the bars Yfrom being completely disengaged when eX- tended. n

Another pair of legs 17 are provided with transverse heads 18 at their upper ends, which are rotatably engaged upon the bars 16 midway'in their length. These legs 17 are provided withr sleeves 19 at their `lower end', containing''slots'2O` so that they may be A Vraised and engaged with the opposite frame bars 14, when thel bed frame is in a collapsed position.

Between each pair of the corner posts 10,

at the head and foot are pairs of forks 21,'

pivoted on pins 22, these forks being engaged with tubular yelements 23, normallyY extending horizontally toward each other,`

one of each pair of theVV elements containing screw threads receptive of the threaded ends 24 of rods 25, the smooth', opposite ends of which slidably engage in the oppositely disposed eleineiits 23; circum] aeent to the Ltubular elements 28 are other-pairs of tubes '26 arranged in two uniform sections and connected by the hinges 27.

Formed through the walls ofthe outer tubes 26 are slotted openingsV 28 and 29, engageable in which are spring actuated detents 30 secured in recesses formed inthe inner tubes 23, the arrangement being such that when the detents 30 are engaged with the-openingsv 29, thezparts are held closely together, while, if the parts be separated, the detents will engage in the openings 28,

thereby holding the parts locked in spaced relation, at which time the joints mayV be broken on the hinges 27, the rods 25at Ythat time being retracted from the center, while V obviously, when in a closed position and the detents are in the openings 29,*the joints cannot be broken upon the hinges due to theV e'iiect of the rods 25.

From the foregoing it will be seen that a substantial and practical embodiment of a tubular bed frame has been presented which will be found a convenient adjunct ifor household purposes, as it may be so eX- pand'ed for the use of two or more persons, or shortened in length so thatit will accommodate children or, vwhen not required for use, be so folded as to be disposed in a small space; v

Having thus described my invention end set forth the manner of its Construction, application end use what claim as new and desire to secure by Letters Patent, is-

:r 1. In a telescopio bed, the oombinetion with the Corner posts thereof, tubular bars extending from diagonally opposite Corners, telescopic elements formed from the other opposite corners engegeeble with said tubular bers, means for preventing the separation of .all of seid elements, and an auxiliary pair ried on seid telescopio elements, and Ineens for limiting the ultimate movement of seid telescopio elements, of pairs of cross elements extended between said pairs of corner posts, said cross elements being pivot-ally engaged with the posts, and consisting of telescopio elements, stiilening rods .in said telescopio elements, sectional tubes enveloping seid telescopio elements, hinges connecting the sections o seid tubes et their center, and ineens for holding seid tubes when in en extended or retracted posiuzionj said elements when in a fully extended position being adapted to fold upon said hinges.

3. In e telescopio bed, the combination with the four posts thereof, and connections extending from side to side between said posts, of pairs of sectional connections between each pair of posts at the head andV foot thereof7 rods rigidly engaged in one section of said connections extending into the other of sections? tnbes surrounding said connections, seid tubes being 'formed in seotions, hinges connecting the sections together, and means formed with seid tele seopie elements for engaging' seid `tubes whereby they may be held in either en extended or retracted position.

In testimony whereof I have aliixed my signature. Y
